Abstract

Purpose

Industry 4.0 has offered significant potential for manufacturing firms to alter and rethink their business models, production processes, strategies and objectives. Manufacturing organizations have recently undergone substantial transformation due to Industry 4.0 technologies. Hence, to successfully deploy and embed Industry 4.0 technologies in their organizational operations and practices, businesses must assess their adoption readiness. For this purpose, a multi-dimensional analytical indicator methodology has been developed to measure Industry 4.0 maturity and preparedness.

Design/methodology/approach

A weighted average method was adopted to assess the Industry 4.0 readiness using a case study from a steel manufacturing organization.

Findings

The result revealed that the firm ranks between Industry 2.0 and Industry 3.0, with an overall score of 2.32. This means that the organization is yet to achieve Industry 4.0 mature and ready organization.

Practical implications

The multi-dimensional indicator framework proposed can be used by managers, policymakers, practitioners and researchers to assess the current status of organizations in terms of Industry 4.0 maturity and readiness as well as undertake a practical diagnosis and prognosis of systems and processes for its future adoption.

Originality/value

Although research on Industry 4.0 maturity models has grown exponentially in recent years, this study is the first to develop a multi-dimensional analytical indicator to measure Industry 4.0 maturity and readiness.

Abstract

Purpose

This study aims to investigate the mechanical properties of sustainable recycled polypropylene (rPP) composite materials integrated with spherical silicon carbide (SiC) particles.

Design/methodology/approach

A representative volume element (RVE) analysis is employed to predict the Young’s modulus of rPP filled with spherical-shaped SiC at varying volume percentages (i.e. 10, 20 and 30%).

Findings

The investigation reveals that the highest values of Young’s modulus, tensile strength, flexural strength and mode 1 frequency are observed for the 30% rPP/SiC samples, exhibiting increases of 115, 116, 62 and 15%, respectively, compared to pure rPP. Fractography analysis confirms the ductile nature of pure rPP and the brittle behavior of the 30% rPP/SiC composite. Moreover, the RVE method predicts Young’s modulus more accurate than micromechanical models, aligning closely with experimental results. Additionally, results from ANSYS simulation tests show tensile strength, flexural strength and frequency within a 10% error range when compared to experimental data.

Originality/value

This study contributes to the field by demonstrating the mechanical enhancements achievable through the incorporation of sustainable materials like rPP/SiC, thereby promoting environmentally friendly engineering solutions.

Abstract

Purpose

The purpose of this paper is to assess multidimensional body image concerns in a sample of obese women seeking bariatric surgery at an outpatient hospital clinic in Hamilton, Ontario, Canada.

Design/methodology/approach

A sample of obese adult women seeking bariatric surgery at an outpatient medical clinic in Hamilton, Ontario, Canada (n=148) completed various self-report measures of body image concerns, including body image dysphoria, body image quality of life, body image investment, and appearance satisfaction. Participant scores were compared to normative data. Correlations between body image concern measures and body mass index (BMI) were examined.

Findings

Participants endorsed more body image dysphoria, more negative body image quality of life, and less appearance satisfaction than normative samples. BMI was not correlated with body image concern scores.

Practical implications

Interventions aimed at reducing body image disturbance in obese women should target multiple components of body image concern. Decisions about who should receive interventions should not be based on BMI status.

Originality/value

The majority of research on body image concerns focuses exclusively on evaluative constructs such as body image dissatisfaction. The current study examined affective, cognitive, and behavioural body image constructs. A better understanding of the multidimensional nature of body image concerns in obese women seeking bariatric surgery informs the development of effective, targeted interventions.

Abstract

Purpose

Despite a lot of agricultural initiatives by the government in a regionally diversified country like India, agriculture is poor, and farmer suicide cases are rampant. This study aims to socially transform and bring behavioural change among the farmers of southern India through the usage of new media. The research has gauged the factors that affect new media accessibility and usability, hindrances in the process and change of farmer’s behaviour through online social marketing bringing social transformation.

Design/methodology/approach

The study is action participatory in nature, and the data is triangulated by conducting a survey at the first level using the Delphi technique among 184 rural south Indian farmers who are smartphone users use new media, and at the next level, the farmers were requested to use WhatsApp for agricultural new sharing, and in the last stage, personal interview with entrepreneurs and farmers has been conducted to understand their new media adoption, e-learning and online social marketing.

Findings

New media is the best way to transform agricultural practices socially. It is a forum where all the farmers of the country can get together and address the issue of the agrarian crisis. Online social marketing (OSM) through WhatsApp is one of the best methods of behavioural change because different farmers can share their experiences and emotion for the crisis and give an appropriate solution to a problem. And, one of the most important features of OSM is it removes third parties from miscellaneous issues be it selling, buying or seeking and sharing information.

Research limitations/implications

Despite trying to cover different hindrances in the way of social marketing of agriculture, the study is not free without its limitations. Language was a barrier, and this study require a lot of time to perceive the changes and adoption. Also, due to time constraint, the authors have categorically clubbed innovators, early adopters and early majority in the same layer opinion leaders and adopters of innovation. These could be analyzed separately in five layers, as suggested by Rogers (1995).

Practical implications

From the managerial perspective, the government should extend services that teach the agriculturists, farmers the use of new media. The marketers and makers of apps and software can tap into this business for launching products for farmers. We need apps designed only for farmers, where agricultural and farming practitioners all over the country and globe can interact about their products, conditions of agriculture and give solution to issues arising in agriculture and farming.

Originality/value

The researchers posit that there are hardly any studies that provide strategies to the agricultural and farming sectors in a regionally diversified country like India. The study is one of its first kind to propose new media strategies to reach out to the farmers of different regions and segmentation for a behavioural change and adoption of new media for better and sustainable agriculture. It has gauged into the factors that affect new media accessibility and usability among farmers and simultaneously gave strategy for behavioural change.

Abstract

Purpose

A huge number of events can affect the operations of a long and complicated supply chain. This paper deals with the development of a supply chain risk mitigation index (SCRMI) based on a risk mitigation maturity framework. A comprehensive list of supply chain risks has been ascertained and segregated into risks faced at various supply chain echelons through a detailed literature review.

Design/methodology/approach

This paper is based on an extensive literature review and questionnaire to identify risks. order of magnitude analytic hierarchy process (OM-AHP) was used as the methodology to assess the prioritization of supply chain risks under two clusters, viz., Probability and severity leading to risk were tested in a distillery.

Findings

SCRMI was determined and used to categorize their maturity level in facing supply chain risks. Thus, organization can focus on improvements for their specific needs.

Research limitations/implications

The model was tested in the distillery industry. It should be tested in other contexts with other methods to provide generalizability.

Practical implications

This research provides direction to managers for choosing risk mitigation strategies based on the global supply chain environment. SCRMI can be a performance metric for the supply chain managers.

Originality/value

The manufacturer's readiness to take action in the face of disruptions in the supply chain is a critical challenge in today's complex business environment and SCRMI framework is instrumental in such business environment.

Abstract

Purpose

This paper aims to explore the antecedents of service robots’ adoption at restaurants in India, specifically focusing on Gen Z customers. This study sheds light on customer preferences in getting served by service robots with the moderating role of human service preference and the perceived job lose orientation of dine-in customers.

Design/methodology/approach

Primary data was collected from Gen Z customers using purposive sampling from prime cities in South (n = 363) and North India (n = 303). The perceptions of respondents towards service robots were analysed in SmartPLS 3.3.9.

Findings

The findings suggest that performance expectancy, effort expectancy, social influence, facilitating conditions, hedonic motivations and price value significantly determine service robots’ acceptance by Gen Z consumers. However, such direct associations are significantly moderated by Gen Z’s human service preference and perceived job loss. Furthermore, demographic factors like respondents’ location, i.e. north and south, affect their preferences.

Originality/value

This research provides more insights into human preferences in dining in terms of moderating variables like human service preference and job-saving orientation of customers based on which the managers can design people, processes and physical evidence strategies of restaurant service mix.

Abstract

Purpose

Increased urbanization has resulted in physical environments, including servicescapes, dominated by functional designs, with nature’s presence becoming scarcer. While “biophilia” designs have received attention in fields like environmental psychology and architecture, studies on biophilia in servicescapes remain scant, fragmented and often contextual. The purpose of this study is to do a semi-systematic review of studies on biophilia in physical servicescape designs (interior and exterior), identify prevailing critical gaps and develop a comprehensive framework for theory advancements in biophilic servicescapes.

Design/methodology/approach

Drawing from a critical review of 56 servicescape studies over 33 years and incorporating theoretical frameworks from environmental psychology, this paper introduces a typology of biophilia in physical servicescapes that includes direct, indirect and human–nature relationships. Furthermore, this study develops a conceptual framework using the Stimulus-Organism-Response model to systematically synthesize biophilia’s overall applicability in servicescapes for consumers and service employees, incorporating moderating factors related to service, servicescape and user types.

Findings

This review investigates the emergence and definition of biophilia in servicescapes, examines the benefits of biophilic design for consumers and service employees and highlights key design strategies. In the absence of robust frameworks to assess biophilia’s impact on consumer and employee responses, this paper presents a comprehensive framework and offers guidelines for future research in retail environments and servicescapes.

Originality/value

Drawing from the synthesis of research on biophilia in servicescapes, this study introduces a framework that demonstrates how antecedent variables, including both direct and indirect biophilic elements, foster human–nature relationships that lead to affective, cognitive and behavioral responses. These effects are moderated by situational factors (e.g. service and servicescape types) and individual differences (e.g. personality, values and nature-relatedness). Ultimately, these responses influence approach or avoidance behaviors in consumers and employees, with a taxonomy detailing responses aligned with biophilia.

Abstract

Purpose

The purpose of this study is to refine the microstructure and improve the corrosion behaviour of aluminium alloy AA5083 by subjecting it to friction stir processing (FSP).

Design/methodology/approach

FSP trials are conducted as per central composite design, by varying tool rotation speed, tool traverse speed and shoulder diameter at three levels. The microstructure is examined and the hardness is measured for both the base material and the processed workpieces. The corrosion behaviour of the base material and processed workpieces is studied using potentiodynamic polarization technique for three different testing temperatures, and the corrosion current and corrosion rate are calculated.

Findings

The results reveal that FSP refined the grains, dispersed secondary phases, increased the hardness and improved the corrosion resistance of most of the friction stir processed specimens than the base material at all the three testing temperatures. Grain refinement and fine dispersion of ß phase improves the hardness and corrosion resistance of most of the FSPed specimens. However partial dissolution of ß phase decreases the hardness in some of the specimens. Most of the FSPed specimens displayed more positive potential than the base material at all the testing temperatures representing a higher nobility than the base material, as a result of fine dispersion of secondary phase particles in the matrix. Large pits formed on the surface of the base specimen indicating a higher corrosion rate at all three testing temperatures. The SEM image of FSPed specimens reveals the occurrence of very few pits and minimal corrosion products on the surface, which indicates lower corrosion rate.

Originality/value

The corrosion mechanism of the friction stir-processed AA5083 specimens is found to be a combination of activation and concentration polarization.

Abstract

Purpose

Many organizations have reported significant benefits after the implementation of Lean Six Sigma (LSS). Embracing LSS requires asking some important questions: How Lean Six Sigma Readiness (LESIRE) can be measured? How can an organization identify the barriers for LESIRE? Answers to these questions are critical to both academicians and practitioners. The paper aims to discuss this issue.

Design/methodology/approach

This study illustrates the development process of a Lean Six Sigma Readiness (LESIRE) evaluation model to assess an organization’s readiness for LSS deployment using the fuzzy approach. The model was developed from 4 enablers, 16 criteria and 46 attributes of LSS, identified through a literature review.

Findings

To demonstrate the efficiency of the model, this study testing the LESIRE evaluation model in three Indian SMEs. Using experts’ ratings and weight, the researchers calculated the Fuzzy Lean Six Sigma index (FLSS) which indicates the LESIRE level of an organization and the Fuzzy Performance Importance Index (FPII) that helps to identify the barriers for LESIRE.

Research limitations/implications

The main limitations of this study are that it did not consider the failure factors of LSS for model development and the LESIRE was only tested in manufacturing industries. Thus, future researchers could focus on developing a model with failure factors. The results obtained from the SMEs show that LESIRE is capable of assessing LESIRE in an industrial scenario and helps practitioners to measure LESIRE for the future decision making process.

Practical implications

The LESIRE model is easy to understand and use without much computation complexity. This simplicity makes the LESIRE evaluation model unique from other LSS models. Further, LESIRE was tested in three different SMEs, and it aided them to identify and improve their weak areas, thereby readying them for LSS deployment.

Originality/value

The main contribution of this study it proposes a LESIRE model that evaluates the organization for FLSS and FPII for LESIRE, which is essential for the organization embarking on an LSS journey. Further, it improves the readiness of the organization that is already practicing LSS.
